## Version 1.3 -- Development snapshot G -- November 2015 ##
### New Feature: ###
- GPS Tracker beacons are now available for the Windows version. Previously this was only in the Linux version.
- Implemented AGW network protocol 'M' message for sending UNPROTO information without digipeater path.
### Bugs Fixed: ###
- Tracker beacons were not always updating the location properly.
- In Mac OSX version: Assertion failed: (adev[a].inbuf_size_in_bytes >= 100 && adev[a].inbuf_size_in_bytes <= 32768), function audio_get, file audio_portaudio.c, line 917.

*
* Module: dwgps.c
*
* Purpose: Interface to location data, i.e. GPS receiver.
* Purpose: Interface for obtaining location from GPS.
*
* Description: Tracker beacons need to know the current location.
* At this time, I can't think of any other reason why
* we would need this information.
* Description: This is a wrapper for two different implementations:
*
* For Linux, we use gpsd and libgps.
* This has the extra benefit that the system clock can
* be set from the GPS signal.
* (1) Read NMEA sentences from a serial port (or USB
* that looks line one). Available for all platforms.
*
* Not yet implemented for Windows. Not sure how yet.
* The Windows location API is new in Windows 7.
* At the end of 2013, about 1/3 of Windows users are
* still using XP so that still needs to be supported.
* (2) Read from gpsd. Not available for Windows.
* Including this is optional because it depends
* on another external software component.
*
* Reference:
*
* API: dwgps_init Connect to data stream at start up time.
*
* dwgps_read Return most recent location to application.
*
* dwgps_print Print contents of structure for debugging.
*
* dwgps_term Shutdown on exit.
*
*
* from below: dwgps_set_data Called from other two implementations to
* save data until it is needed.

Idea for future enhancement:
A couple people have asked about support for the DMK URI.
This uses a C-Media CM108/CM119 with one interesting addition, a GPIO
pin is used to drive PTT. Here is some related information.
DMK URI:

Idea for future:
On the RPi, the device path for GPIO number XX is /sys/class/gpio/gpioXX.
There was a report that it is different for the Cubieboard. For instance
GPIO 61 has gpio61_pi13 in the path. This indicates connector "i" pin 13.
For another similar single board computer, we find the same thing:
https://www.olimex.com/wiki/A20-OLinuXino-LIME#GPIO_under_Linux
How should we deal with this? Some possibilities:
(1) The user might explicitly mention the name in direwolf.conf.
(2) We might be able to find the names in some system device config file.
(3) Get a directory listing of /sys/class/gpio then search for a
matching name. Suppose we wanted GPIO 61. First look for an exact
match to "gpio61". If that is not found, look for something
matching the pattern "gpio61_*".

APRS SYMBOL OVERLAY and EXTENSION TABLES in APRS 1.2 29 Oct 2015

BACKGROUND: This file addresses new additions proposals (OVERLAYS)
to the APRS symbol set after 1 October 2007. The master symbol
document remains on the www.aprs.org/symbols/symbolsX.txt page.
document remains on the www.aprs.org/symbols/symbolsX.txt page, but
only has one line per symbol character. Since each of the symbols
can have up to 36 overlays, this gives us thousands of symbols codes.
NOTE: There was confusion with different copies of this file on
different web pages and links. THIS file is now assumed to be the
CORRECT one.
Update 29 Oct 2015: Reorgainized list to Alphabetical Order.
+ Added many new Balloons (due to lost DoD radar Blimp yesterday)
+ Confirmed D^ for Drones was already in there since 2014
+ Added R^ type aircraft for remotely piloted
